Remote control device

The invention relates to a remote controller, in particular to a remote control device with good waterproofness.

With the advancement of technology, various electronic remote controls are widely used in remote electronic control mechanisms such as various types of steam locomotives, iron shutter doors or anti-theft remote controls. Waterproof design is extremely important because the electronic components in the electronic remote control are easily damaged by moisture.

Referring to Figure 1, the new patent case of the "Multi-point Closed Waterproof Remote Control" of the Republic of China Announcement No. M473652 is a waterproof improvement design for the remote control. The utility model mainly comprises an upper cover 11, a cover 12 for covering the upper cover 11, a circuit board 13 placed in the lower cover 12, a pressing block 14 provided with a plurality of buttons 141, and an elastic piece. 15, and a sliding cover 16 disposed on the upper cover 11. The top edge of the lower cover 12 is retracted to form a flat surface 121, and a convex portion 122 protruding upward from the flat surface 121. The elastic piece 15 is disposed above the circuit board 13 and disposed on the tenon 122. The elastic piece 15 is convexly disposed with a plurality of positioning blocks 151 for being embedded in the buttons 141 of the pressing block 14. Two locking holes 112 are respectively disposed at two ends of the downward opening 111 of the upper cover 11 , and a protrusion is respectively disposed on each side of each of the locking holes 112 . 113, the two screw holes 124 are respectively disposed on the two ends of the upper opening 123 of the lower cover 12, and the sills 125 corresponding to the protrusions 113 of the upper cover 11 are respectively disposed on the two sides of the screw holes 124.
